"You mean we're going to be in the real spy business?" Chavez asked. It would be his first time ever. Most of the time he and Clark had been paramilitary operators, doing jobs either too dangerous or too unusual for regular field officers.

"It's been a while for me too, Ding. Oleg, I never asked what language you used working your people."

"Always English," Lyalin answered. "I never let on my abilities in Japanese. I often picked up information that way. They thought they could chat right past me."

Cute, Clark thought, you just stood there with the open-mouth-dog look on your face and people never seemed to catch on. Except that in his case, and Ding's, it would be quite real. Well, the real mission wasn't to play spymaster, was it, and they were prepared enough for what they were supposed to do, John told himself. They would leave on Tuesday for Korea.

In yet another case of interagency cooperation, a UH-1H helicopter of the Tennessee National Guard lifted Rebecca Upton, three other men, and the gasoline tanks to Oak Ridge National Laboratory. The tanks were wrapped in clear plastic and were strapped into place as though they were passengers themselves.

Oak Ridge's history went back to the early 1940's, when it had been part of the original Manhattan Engineering Project, the cover name for the first atomic-bomb effort. Huge buildings housed the still-operating uranium-separation machinery, though much else had changed including the addition of a helipad.

The Huey circled once to get a read on the wind, then settled in. An armed guard shepherded the party inside, where they found a senior scientist and two lab techs waiting—the Secretary of Energy himself had called them in this Saturday evening.

The scientific side of the case was decided in less than an hour. More time would be required for additional testing. The entire NTSB report would address such issues as the seat belts, the efficacy of the child-safety seats in the Denton car, how the air bags had performed, and so forth, but everyone knew that the important part, the cause of five American deaths, was that the Cresta gas tanks had been made of improperly treated steel that had corroded down to a third of its expected structural strength. The rough draft of that finding was typed up—badly—on a nearby word processor, printed, and faxed to DOT headquarters, adjacent to the Smithsonian Air and Space Museum in Washington. Though PRELIMINARY FINDING was the header on the two-page memo, the information would be treated as Holy Writ. Most remarkably of all, Rebecca Upton thought, it had all been accomplished in less than sixteen hours. She'd never seen the government move so fast on anything. What a shame that it didn't always do that, she thought as she dozed off in the back of the helicopter during the return flight to Nashville.
